The word "Thanksgiving" is a transparent compound formed from two native English elements. The first element, "thanks," originates from the Old English noun þanc, which carried the dual meanings of "thought" and "gratitude," reflecting the internal sentiment that precedes outward expression. The second element, "giving," derives from the Old English verb giefan, meaning "to bestow." When combined, the compound literally denotes "the giving of thanks." Historically, the term was used in a general religious context for ceremonies expressing gratitude to God. Its specific association with the annual national holiday originates from the 17th-century harvest celebrations by Pilgrim settlers in North America, which later became institutionalized.
